This construction alsocauses the dog, when closed, to forma reinforcing abutment at theextremity of .the'hook 7 member If! enabling the needle safely to resistheavy pressure applied to it's eyeleted end.

Owing to the fact that, when'the dog is closed,

its, free end 'is directedaway from the pointed end of the needle,the'movements of the needle thru the work tend to keep the dog in theclosed position. I

It will be observed that; at each side of its grooved portion, thedog l5has a sharpedge as viewed in cross section. These sharp edge portions ofthe dog'p'ass close to each side of the needle shank 6 as the dog isswung to its closed knife-edge or angular shoulder 22 along one side ofsaid'shank. The adjacent sharp-edged portion of the dogcooperateswith'this knife edge,-and thus forms a cutting meansfor'severing by a shearing action the thread or twine carriedby theneedle, at the'close of a sewing operation.

The stop shoulder '23 prevents the knife edge of the shankli from beingblunted by contacting with the base of the slot I6.

It should be understood thatthe present disclosure is for the purpose ofillustration only and 7 that this invention includes all modificationsand ,equivalents which fall within the scope of the entrance openingand'with a dog pivoted to swing subject matter claimed; 7

What is claimed is:--

1. A, needle of the kind described having through it an' eye whichis-furnished with an to and from a position for closing said entranceopening, said needle having a shouldered portion adjacent tov said eyeand said dog having a sharp edge portion positioned to cooperate withsaid shouldered portion of the needle to sever the V 7 thread after asewing operation.

2."A needle of the kind described having through itan eye which isfurnished with an entrance opening and with a dog pivoted to swing toand from a position for closing said entrance opening, said needlehaving a shank provided with aflattened portionadjacent to said eye andsaid dog having a' longitudinally grooved portionjfittable oversaid'fiattened portion, said' dog having alsoa sharp edge portion at atleast shank to provide a thread cutting means.

3.
